The mobile Internet has become increasingly visible in everyday life. As mobile Internet penetration leverages content business opportunities, it is crucial to identify methodologies to fit mobile-specific demands, e.g. regularity. Regularity is one of the important measures to capture easy-come, easy-go mobile users, especially in subscription-based mobile services. The author proposes a method called the "time slot count in window" method (TCW-method) to efficiently capture regular users, while relaxing the explicit splits among time slots with visits. The author shows the case study result from 2001-2002 commercial service logs. Case studies conducted in 2001-2002 with commercial news service subscribers show that the relaxation in the proposed method loses 2-3 % in the true positive rate of regularity as a binary classifier. The results show high true positive rate, 88-91 % for the Carrier-A case and 86-92 % in the Carrier-C case. Experimental results show that the method is promising for identifying revisiting users under mobile-specific constraints..
